Yea, to use avr is more comfortable than pics but there is a real problem.Microchip distributes their products to everywhere but avr does not. For example i couldn't find avr in my country.(Europe)
Currently, ,a design include an Atmel ATtiny26L (20 pins) device in it. Is it going to be cheaper if it change to a PIC 16F628A (18 pins device) ? My quantity is about 10K per month.

Why not just ask your distbutors of PIC and AVR for prices in big quantities?
I single unit prices it seems that the 16F628A is a bit cheaper, but it can't perform as fast as ATtiny 26L.
16F628A < 5MIPS
ATtiny26L < 8MIPS
The PIC16F628A also have less features:
One PWM
No ADC
ATtiny26L:
2 PWMs
10-bit ADCs:
- 11 Single Ended Channels
- 8 Differential ADC Channels
- 7 Differential ADC Channel Pairs with Programmable Gain (1x, 20x)
But if you doesn't need any of these features maybe you should go for the PIC or look for a cheaper AVR alternative.
I don't know about the prices in big quantities though, but ask your distriboturs.
Or maybe you should use the ATtiny2313L instead of ATtiny26L.
Samples of the ATtiny2313 are to be released Q3/03.
ATtiny2313 contains no ADCs and I think it is going to be cheaper than ATtiny26.
This is from the pdf above: Die Shrinks
To reduce cost, improve speed and the feature set of the devices, ATMEL
is currently shrinking some of the AVR devices.
AT90S1200 Will be replaced with the pin compatible ATTINY2313.
AT90S2313 Will be shrunk into the pin and functional compatible ATTINY2313.
ATTINY12 Will be replaced with the pin compatible ATTINY13.
ATTINY15 Will be shrunk into the pin compatible ATTINY13.
That's true, but this is because the PIC is 20 years old or so. The AVR family is much newer and more modern in design (more c friendly).
The AVR is getting more and more common at the expense of PIC's.
Microchip have introduced the new 18Fxxx family, which is supposed to be more c friendly than older PIC familes.
1)MSP430FXXX--- WHEN SPEED IS NOT AN ISSUE
THEY ARE CHEAP,VERY CHEAP!, VERY LOW POWER,FLASH
SMALL PACKAGES.
2)CYGNAL WHEN YOU NEED TO RUN
a 25 mips part por $0.99 in a tiny msp11 package
or a 100 mips C8051F120
Both of these chips have JTAG interfaces that make it a JOY to develop.
Example i just finish a device using a MSP430F413 with LCD miltiplex drivers .I'm using a 4 digits 7 segment brand new LCD from LUMEX
the whole SOLUTION CPU + LCD = $3 .Yes THREE BUCKS
BEAT THAT !
